After mining operations,a large number of broken ore pillars will be left behind,forming a group of ore pillars.The group of ore pillars is of great significance for safe underground operations and the recovery of ore pillars resources.Under the influence of high ground stress,geological weak surface structure,free face generation,blasting vibration and other factors,the ore pillars group is very prone to instability,collapse,resulting in disaster of a large area of instability ore pillars group,thus causing great harm to underground workers and equipment.In order to strengthen the safety control of the mine pillars group,the stability analysis was carried out based on the renormalization group theory and Bayesian network.The renormalization group is a scaling transformation group.The self-similarity transformation of the basic unit can be used to describe the whole system,which is similar to the process in which the instability of a single pillar ultimately leads to the instability of the pillars group.Bayesian network can also overcome the uncertainty in the process of the instability of the pillars group.Therefore,based on the renormalization group theory and Bayesian network,the stability analysis model of pillars group was established.A pillars group in Tongkeng mine was taking as the research object.Firstly,the critical instability probability of the pillars group was derived based on the two-dimensional renormalization group model.Secondly,the multiple logistic regression model was used to deduce the calculation formula of the instability probability of a single pillar,then the stability,instability and instability probability of the pillar was calculated,and the stability probability of a single pillar was input into the Bayesian network to obtain the instability probability of the pillars group.Finally,by comparing with the critical instability probability of the pillars group obtained from the two-dimensional renormalization group model,the stability group of the pillars group was obtained.The research results show that this method can more accurately obtain the instability probability of the ore pillars group,and by defining the stability probability of a single ore pillar to carry out Bayesian network probability inversion and sensitivity analysis on the ore pillars,can design the optimal mining route of the ore pillars,and achieve safe,efficient and low loss recovery of pillars resources in the panel.This method can also provide reference for stability analysis and pillars resource recovery of similar mine pillar groups.
